Staafankers

Staafankers are a type of anchoring device used in construction and engineering. Their primary purpose is to secure elements to a substrate, such as concrete or masonry. A staafanker typically consists of a metal rod, often steel, which is inserted into a pre-drilled hole. The anchoring mechanism can vary. Some staafankers rely on expansion, where the rod is driven or screwed, causing an expansion sleeve to tighten against the walls of the hole. Others are chemical anchors, where a resin or adhesive is injected into the hole before the rod is inserted, creating a strong bond. The design and material of a staafanker are chosen based on the expected loads, the type of substrate, and the environmental conditions. They are commonly used for applications such as fastening structural steel, mounting machinery, and installing façade elements. Proper installation is crucial for the integrity and load-bearing capacity of the staafanker. This usually involves cleaning the hole, correct placement of the anchor, and following the manufacturer's specifications for curing times in the case of chemical anchors.
